 be going on here, as might be expected with the mighty sub- 

 marine current rolling its saline waters into the strata occupying

 considerably less saline water, the temperature is slightly, and 

 the salinity greatly, reduced ; thereby the density also decreases, 

 becoming lower than that of the deepest layers of the Atlantic 

 region, although higher than that of the surface layers. This
